摘要：

自显生宙以来,中国西北地区经历了中元古代至早古生代的板块离散、晚古生代至三叠纪末的板块敛合碰撞、侏罗纪至第四纪的盆山体制三个主要发展阶段,形成了三大类、十一亚类主要类型盆地。盆地在纵向上往往具"先张后压"的双层结构特征。

Abstract:

Northwest China had experienced three major development stages,i.e.plate diver-gence from Middle Proterozoic to Early Paleozoic;plate convergence from Late Paleozoic to the end of Triassic;basin-mountain mechanism from Jurassic to Quaternary.The transformation between the tectonic mechanisms of oceanic and continental lithospheres,together with the influence exerted by the Tethys Plate since Meso-Cenozoicresu lted in three type basins(tensional,compresional and strike-slip.basins)and eleven subtype basins.Multicycle is the basic characteristic of the superimposed basins in this area.The basins extended first and then compressed,thus forming double-layer structure in verti-cle.The extention provided ideal place for the deposition of source rocks and the compres-sion prepared necessary condition for hydrocarbon migration ahd accumulation.
